From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041020 Firefox/0.10.1 Description of problem: The scp command from openssh package sometimes returns wrong exit code. The file is transferred correctly. Exit code is wrong. If I scp from Linux box to Linux box: OK If I scp from Linux FC3 box to Solaris box: ERROR If I scp from Linux RH73 box to Solaris box: OK If I scp from Solaris box to Linux box: OK If I scp from Solaris box to Solaris box: OK The only problem is when scp command on Fedora Core 3 is connecting to server on Solaris 9. Same thing using scp command on Red Hat 7.3 works correctly. All other combinations work correctly. My wild guess is that there's something wrong with the client on FC3. The SSH server on Solaris box is the one that comes with Solaris 9. BTW, it might be related. When I ssh from FC3 box to Solaris9 box, and then logout, ssh session sometimes hangs (not always reproducable). Escape key sequence doesn't work. I need to either kill ssh process from another window, or close the window with hung session. Version-Release number of selected component (if applicable): openssh-3.9p1-7 How reproducible: Always Steps to Reproduce: 1. From FC3 box: scp filename solaris9-box: 2. echo $? Actual Results: echo $? returns 1 Expected Results: It should return 0 Additional info:
Can you try openssh-4.0p1 from FC development? However you would need to rebuild it from .src.rpm if you don't want to upgrade other packages to FC development. Also could you try to post a log which is produced when running scp to the Solaris box with -v option.
I've upgraded my machine to CentOS 4 recently (distro built from RHEL 4 SRPMs, basically a clone). Bug was still present (openssh-3.9p1-8.RHEL4.1). Then I rebuilt openssh package from FC development tree and installed it (openssh-4.0p1-2) and got the same error. This menas that bug is present in: - FC3 - FC devel - RHEL4 I will include scp -v from both openssh-3.9p1-8.RHEL4.1 and openssh-4.0p1-2 as attachments. Diff on the files doesn't show any differences (other than version numbers, and some other unimportant details).
Created attachment 112757 [details] scp -v on CentOS4/RHEL4
Created attachment 112758 [details] scp -v of FC-devel built on CentOS4/RHEL4
The problem is that the local scp only executes scp on the remote machine through the ssh connection. The remote scp returns -1 and this exit status (!= 0) is translated in the local scp as 1. The problem lies on the Solaris side not on the FC side.
OK, how do you than explain than openssh as distributed with Red Hat 7.3 works just fine? Plus, Solaris to Solaris also works fine. And more or less anything-else (other than openssh 3.9+) to Solaris works fine. IMO, something on the FC side is triggering Solaris side to return -1.
I'd suppose the problem could lie in the versions of the openssh on the systems. You can try to report that upstream to OpenSSH bugzilla http://bugzilla.mindrot.org/
